Specification of Letters Patent" Patented Dec. a, T921,

Application filed. March 1, 1920. terial No. 362,319.

To all whom it may concern Be it known that I, HERMAN C. Hnasorrr, a citizen of the United States, residing at Minneapolis, county of Hennepin, State of Minnesota, have invented certain new and useful Improvements in Wringers, of which the following is a specification.

Tn the operation of a clothes wringer, provision is made for quick release of the action of one wringer roll upon the other to avoid injury to the fingers or hand of the operator and to enable the operator to withdraw any article from between the rolls during the wringing operation. Generally in these wringer roll releasing devices the lower roll is positively driven and continues its operation when the rolls have been separated and it is desirable to positively. stop revolution of the'lower roll when the wringing operation ceases. v

The object of my invention is to provide a driving means which, when the rolls are separated, will be automatically disconnected from-both rolls and will remain so disconnected until the two rolls are again adjusted in their working position.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

Tn the accompanying drawings forming part of this.specification,

Figure 1 is a longltudmal sectional view through the wringer embodying my inven- Fig.v is a, longitudinal sectional view showing the *relative position ofthe rolls when the release device has been operated,

titl- Fig. 3. is a-transverse sectional view on the line 33 of Fig. 1,

Fig. dis a transverse sectional view on the lined-4 of Fig. 2. I Tn the drawing, 2 represents the metallic frame of the wringer. 3 is a housing for the upper end of the drive shaft 4 on which a beveled pinion-5 is mounted meshing with a gear 6 on a short shaft 7 that is journaled in bearings 8. A pinion 9 is mounted on the end. of the shaft 8 meshing with" a similar pinion 1001s an .efitension of theshaft ll of the upper roll 12; -This' -shaft has a ball bearing-13 in a boa 14in the wall of thev housing 15 which'incloses thegear 10.

pinion 17 is mounted onlthe shaft 11 adjatilt cent one end of the roll 12 and a similar pinion 17 is mounted on the shaft at the other end of the roll in a housing 21. A lower roll 18 has a shaft 19 journaled in a housing 2 of the frame 2 in ball bearings 19*, and this shaft is provided with a pinion 20 which meshes with the pinion 17 of the shaft 11. At the opposite end of the roll 18 is a pinion 20 which meshes with the pinion 17 and is inclosed in a housing 21*. The housings 15 and 21 are pivoted at 23 to the housings 2 and 21 and allow the upper roll to be lifted away from the lower roll, said pivots 23 being located on one side of the lower roll and studs 24: being mounted in the frame of the wringer on the other side of the roll and limited against upward movement by a helical spring 25 and provided with lugs 26 which bear on the frame and prevent downward movement of the studs.

The housing 9.21 which extends over the upper roll is provided with a hand grip 27 and is pivoted to the housings l5 and-'21 by pins 28 which are mounted on the housings to engage the recessed upper ends of the studs 24 and lock the upper and slower rolls a in their working position but allowing the through the shaft 11 of theupper roll and i from this it must follow that when the gears,

9 and 10 are separated and by the release of the upper roll from the lower one that the drive to the lower roll will be positively broken and cannot be resumed again until the upper roll is returned to-its working. position. In this way T am able to positively check further revolution of the lower roll as soon as the release is operated to separate the two rolls.

An important. point in the construction, resulting from the stopping of both rolls, is

the complete relief tothe motor of the load.

Tn constructions wherein the lower roll is continuously drivenit often happens that the 'clothes will be wound on this lower roll, resulting in such load that the motor will he stalled orburned out. Tn the improved device there is an absolute relief of the load as "soon as rollsare separated and, consequently, there is; positively no danger of overloading or burning outthe motor.

I claim as myv invention; i r

1. A. clothes wringer comprising a frame having anormally fixed section and a movable section hinged thereto, a roll journaled v in-said fixed section, a roll journaled in said ,"movable section and adapted to be moved 7 10 with said movable section to a non-working position, with respect to said fixed section roll, mechanism spaced from the fixed section roll for normally driving both rolls through the shaft of the movable section roll and being rendered inactive for driving either roll upon movement of said -movable roll. I

2. A clothes wringercomprising a frame having a fixed andv amovable section, a

section and its roll from said fixed: section geared to the shaft of the rollthat i's-mount I ed in said movable section for driving said 'roll and said driving lower roll through-the shaft of the upper shaft becoming inoperative for driving both rolls when said upper roll and its support are moved out of working position with respect to said lower 3. A clothes wringer comprising a metal frame having a fixed portion and a hinged upper portion, a lower wringer roll journaled. in said fixed portion, an upper wringer roll and its section.

roll mounted in said hinged portion and adapted to swing toward and from. said lower roll, said rolls having meshing pinions for driving one roll from the other, and a shaft in axial alinement with and spaced lower roll, a drive shaft havin connection with the shaft of sai driving said lower roll through the shaft having a fixed and a hinged section, a lower wringer roll mounted in said fixed-section, an upper wringer roll mounted in said hinged section, said rolls having meshing 'pinions' for driving one roll from the other, and said pinions becoming separated when said upper roll is moved away from said driviilg upper roll and throiighthe shaft of said upper roll and said pinions with the shaft of the lower roll, ,the movement of said hinged section of the wringer frame-away-from said fixed section separating'said rolls and said driving connection.

5. In combination, a wringer frame having separable sections, a roll journaled in each section, separable intermeshing pinions normally connecting the two rolls, one roll having a gear fixed within its frame section to its shaft, and a drive member mounted in part in the companion frame section for meshing with the gear and separable therefrom upon separating the frame sections.

6. A clothes wringer comprising a frame, a lower wringer roll mounted therein, an upperwringer roll mounted for'movement toward and from said lower roll, said rolls having meshing pinions for driving one roll from the other and said pinions becoming separated when said upper roll is moved away from said lower roll, a drive shaft having a driving connection with the shaft .of said upper roll and through the shaft of the vupper roll and said pinions with the shaft of the lower roll, the connection between said drive shaft and said upper roll becoming inoperative and stopping revolution of both rollswhen the upper roll is moved out of driving engagement with the lower roll. v

- 7. A clothes wrin er comprising a frame having a normally xed and a movable section and wringer rolls mounted therein respectively, said movable section and its roll being mounted for movement bodily away from said fixed section and its roll to an inoperative position, said rolls having meshing pinions for driving one roll from the other-when they are in their normal work ing position, said pinions becoming separelation to the shaft of saidlower roll and geared. to the shaft of the upper roll for rated when said movable section is moved to, its non-working position, a drive shaft operatively connected with the roll of said movable section for driving the roll of said fixed section through said movable section roll and said pimons, the se aration bf saidpinions when said movab c section is moved to its non-working position disconnecting said drive shaft and stopping revolution of both rolls.

In witness whereof, I have hereunto set my hand this25th day of February, 1920.
